Hi! I have recently been given a Sony MZ-N710, it's good but I can't connect it to the PC because I have no drivers (and no SonicStage). Even if I did, they probably wouldn't work properly on XP64 anyway. My problem is that the MiniDisc I am using has had somebody else's stuff on that I cant delete because it's been put on using a PC, and if I try and do anything to it I get TrProtect. I can get into service mode, but it's scary and if I need to I will need to know exactly what to do, because knowing me I would bugger it straight up . I need to know how to do a Full-erase of the disc without a computer. It's a 74-minute disc. Please somebody, help me
